In-depth study of spectroscopic properties of new Pr3+-ion doped low-phonon sesquisulfide Lu2S3 material for mid-IR laser sources

Popis výsledku v původním jazyce

Lu2S3 material from the family of sesquisulfide hosts appears to be a promising low-phonon material for use as a laser gain medium allowing for a laser emission over a broad spectral range from ultraviolet to far mid-infrared wavelengths. In this paper, a praseodymium-ion doped Lu2S3 single crystal grown by micro-pulling down technique is investigated with focus on its spectroscopic properties. The Raman, excitation, and luminescence spectra are presented. By selective excitation of the main energy levels of Pr3+-ions, 26 luminescence transitions of the Pr:Lu2S3 crystal spanning the similar to 0.49 5.5 mu m wavelength range have been identified. The correct assignment of the observed luminescence spectra to the respective Pr3+ energy-level transitions was confirmed by the calculation of the optimized squared reduced-matrix elements for the tensor operators U-(k) and L + gS.
